The saiga antelope breeding season concentrates thousands of individuals in small areas, creating conditions of intense competition and occasional mass mortality that test conservation responses.
Saiga breeding biology creates concentrated moments of both extraordinary life and potential catastrophic death. The synchronous calving period, while adaptive against predators, means that disease outbreaks triggered by climate stress can kill hundreds of thousands of calves in days. Poaching-induced skewed sex ratios mean remaining males are exhausted by extreme competition during the rut, sometimes dying. Conservation that restores balanced sex ratios reduces this welfare burden on individual males.
